2014-09-30bcma: register bcma as device tree driverHauke Mehrtens
This driver is used by the bcm53xx ARM SoC code. Now it is possible to give the address of the chipcommon core in device tree and bcma will search for all the other cores.

2014-09-09bcma: add support for chipcommon B coreHauke Mehrtens
This core is used on BCM4708 to configure the PCIe and USB3 PHYs and it contains the addresses to the Device Management unit. This will be used by the PCIe driver first. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2014-09-09bcma: store more alternative addressesHauke Mehrtens
Each core could have more than one alternative address. There are cores with 8 alternative addresses for different functions. The PHY control in the Chip common B core is done through the 2. alternative address and not the first one.

2014-01-30Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linusLinus Torvalds
Pull MIPS updates from Ralf Baechle: "The most notable new addition inside this pull request is the support for MIPS's latest and greatest core called "inter/proAptiv". The patch series describes this core as follows. "The interAptiv is a power-efficient multi-core microprocessor for use in system-on-chip (SoC) applications. The interAptiv combines a multi-threading pipeline with a coherence manager to deliver improved computational throughput and power efficiency. The interAptiv can contain one to four MIPS32R3 interAptiv cores, system level coherence manager with L2 cache, optional coherent I/O port, and optional floating point unit." The platform specific patches touch all 3 Broadcom families. It adds support for the new Broadcom/Netlogix XLP9xx Soc, building a common BCM63XX SMP kernel for all BCM63XX SoCs regardless of core type/count and full gpio button/led descriptions for BCM47xx. The rest of the series are cleanups and bug fixes that are MIPS generic and consist largely of changes that Imgtec/MIPS had published in their linux-mti-3.10.git stable tree.

2014-01-23bcma: gpio: add own IRQ domainRafał Miłecki
Input GPIO changes can generate interrupts, but we need kind of ACK for them by changing IRQ polarity. This is required to stop hardware from keep generating interrupts and generate another one on the next GPIO state change. This code allows using GPIOs with standard interrupts and add for example GPIO buttons support.

2013-09-26bcma: make bcma_core_pci_{up,down}() callable from atomic contextArend van Spriel
This patch removes the bcma_core_pci_power_save() call from the bcma_core_pci_{up,down}() functions as it tries to schedule thus requiring to call them from non-atomic context. The function bcma_core_pci_power_save() is now exported so the calling module can explicitly use it in non-atomic context. This fixes the 'scheduling while atomic' issue reported by Tod Jackson and Joe Perches.

2013-01-09bgmac: driver for GBit MAC core on BCMA busRafał Miłecki
BCMA is a Broadcom specific bus with devices AKA cores. All recent BCMA based SoCs have gigabit ethernet provided by the GBit MAC core. This patch adds driver for such a cores registering itself as a netdev. It has been tested on a BCM4706 and BCM4718 chipsets. In the kernel tree there is already b44 driver which has some common things with bgmac, however there are many differences that has led to the decision or writing a new driver: 1) GBit MAC cores appear on BCMA bus (not SSB as in case of b44) 2) There is 64bit DMA engine which differs from 32bit one 3) There is no CAM (Content Addressable Memory) in GBit MAC 4) We have 4 TX queues on GBit MAC devices (instead of 1) 5) Many registers have different addresses/values 6) RX header flags are also different The driver in it's state is functional how, however there is of course place for improvements: 1) Supporting more net_device_ops 2) SUpporting more ethtool_ops 3) Unaligned addressing in DMA 4) Writing separated PHY driver Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: David S.

2013-01-03Drivers: bcma: remove __dev* attributes.Greg Kroah-Hartman
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2012-12-06bcma: register watchdog driverHauke Mehrtens
Register the watchdog driver to the system if this is a SoC. Using the watchdog on a non SoC device, like a PCIe card, will make the PCIe card die when the timeout expired, but starting it again is not supported by bcma.

2012-12-06bcma: add methods for watchdog driverHauke Mehrtens
The watchdog driver wants to set the watchdog timeout in ms and not in ticks, which is depending on the SoC type and the clock. Calculate the number of ticks per millisecond and provide two functions for the watchdog driver. Also return the ticks or millisecond the timer was set to in case the provided value was bigger than the max allowed value. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: John W.
